Some good FPS games single player?.

Hi I have been looking for a good single player FPS game for a while now and need help.

Anyone know of any good ones?, Here are the games I have played Half-Life, Half-life Opposing Force, Half-Life 2, UT99, UT 2003, UT 2004, Call of Duty 1, 2, MW1, MW2, and GTA 3 Vice CIty.

Please post your favorite games :D :D.

Bye

Here are my System specs.
Pentium 4 2.8
ATI 4670 1GB AGP
2.5 GB Memory

If you loved Modern Warfare campaign you're gonna love Ghosts too.

Try the two from Wild Flying Hog.

For your system... James Bond Nightfire, Call of Cthulu dark corners of the earth, AVP gold, and AVP2000.

Spec Ops: The Line.

Don't know if your system will run it though.

• Fear
• Kingpin
• Far Cry
• Return To Castle Wolfenstien

No One Lives Forever 1 and 2. They don't make them like that anymore.

I have played No One Lives Forever 1 and 2, they were great. I have also played Farcry which was also good.
Any other games people?, still looking for some great games to play :p.

Black Mesa Source if your computer can handle it.. It's a complete remake of Half-Life 1 with HL2+ visuals and new gameplay.. It's free to boot.

Shadow Warrior , Hard Reset , STALKER Trilogy , Crysis and Crysis Warhead . You should upgrade your PC as well :-)

I second these.

@MechGamer110:

Far cry, Bioshock, Halo Combat Evolved
